There's really very little to complain about here. Speedy DDR5 memory with low latencies and AMD Expo sign-off. For not much more than some 16 GB kits, in fact.

Corsair 4000D Airflow | ATX Mid-tower |Up to 360 mm fans front | Up to 280 mm fans top | 120 mm fan rear | 7.85 kg | $104.99 $79.97 at Amazon (save $25.02, Prime member exclusive deal)
Corsair's compact PC case is pretty basic but has plenty of room inside for lots of fans and graphics cards up to 360 mm (14.2 inches) in length. It's on sale pretty much everywhere and at this price, it's a veritable bargain.

WD Black SN850X | 1 TB | NVMe | PCIe 4.0 | 7,300 MB/s read | 6,300 MB/s write | $114.99 $77.04 at Amazon (save $37.95)
This is our favorite SSD for gaming right now. Unlike the cheaper SN770, the SN850X encapsulates the best PCIe 4.0 offers in terms of performance (check out our review). That makes it a great fit for a boot drive with space to spare for your game library, and at this price, we're happy to pay the premium for its higher speed.

BeQuiet! Dark Rock Pro 5 | dual-tower | seven heat pipes | 2x Silent Wings fans included | $89.90 $63.92 at Amazon (save $25.98)
Forget liquid cooling, we can get by just fine with good ol' traditional air. Not only is air cooling often better value than liquid cooling, it's nice and quiet too. This BeQuiet! cooler is pretty much brand new, by the way.

Acer KC242Y | 23.8-inch | 1080p | 100Hz | VA | FreeSync | $117.99 $89.99 at Amazon (save $28)
Ok, so it's pretty small, and it's a VA panel. But honestly, for this money and from a well-known and trusted manufacturer, with AMD FreeSync and a 100Hz refresh rate? A pretty good deal if you ask us. This would make an excellent second monitor, or a pretty quick main monitor in a pinch if you're building on a very tight budget.

Logitech G502 Lightspeed | Wireless | 25,000 DPI | 11 buttons | $149.99 $75.99 at Amazon (save $74)
Still one of our favorite gaming mice, Amazon is offering a pretty deep discount on the Lightspeed. With its fancy infinite scroll, 11 programmable buttons, modifiable weight, and wireless charging capabilities, it's a great option at this price. And this is the version with the updated 25K sensor, too, as opposed to the 16K of the original model.

The MX Master has been around for years and with good reason—it's one of the best ergonomic mice you can buy. It's pretty heavy and bulky for gaming, but the MagSpeed electromagnetic wheel is glorious for productivity tasks.

Logitech G Pro X Superlight | Wireless | 25,600 DPI | 5 buttons | 70-hour battery | Right-handed | $159.99 $94.99 at Best Buy (save $65)
Ignore the fact that this model has been around for three years or so, as it's still a fantastic lightweight, wireless gaming mouse. One of the best, in fact. This deal's on the black version, but you might also be able to pick it up in a gorgeous white or hot pink.

Asus ROG Strix Scope RX | Mechanical | Wired | Full-size | RGB lighting | $169.99 $79.99 at Amazon (Prime Exclusive, save $90)
We've been big fans of Asus keebs in recent years, and this Strix Scope RX gaming has some features that really make it stand out from the pack. IP57 water and dust-resistance should make it resilient to the odd coffee spill, while the USB 2.0 passthrough feature is a nice touch. The ROG RX red switches are smooth and accurate, and a built-in stealth key hides your apps and mutes audio to prevent embarrassing moments. Stealthy, sleek, and ready for anything, this one.

This is the keyboard our Dave uses each and every day. It's a compact beauty that feels great to the typing touch, but one that can also form the base for all your enthusiast keeb desires. It's got a hot-swappable switch base, silicone and foam dampening, solid stabilizers, RGB, PBT keycaps, and pre-lubed switches, too.

Corsair knows headsets, and the HS80 is no half-measure. It comes with an excellent microphone and great audio quality. And although it can feel a little bulky at 360g, the floating headband design keeps it sitting comfortably on your head.

8BitDo Ultimate | 2.4 GHz Wireless | Charging Dock | $69.99 $55.99 at Amazon (save $14)
As with other 8BitDo controllers, this Ultimate one's primary selling point is its build quality and satisfying touchables (buttons, triggers, sticks), but it's also incredibly comfy, has back paddles, and very decent battery life. Throw in the charging stand for $55.99 with this discount and the retro brand's modern controller is a no-brainer.

Govee Glide Hexa Light Pack of 10 | $179.99 $99.99 at Amazon (save $80)
It's rare to get such high-quality hex lights for under $100, so this $80 discount was always going to put this Govee 10-pack on this list. It comes with the whole slew of smart app and music sync capabilites, too, of course.
